Preparation and Electrochemically Catalytic Hydrogen Evolution of Co(III)corrole Copolymerized with mono-, bis- and tri-Thiophenes

Аннотация

A series of conductive polymers of thiophen-substituted Co^Шcorrole copolymerized with mono-, bis- and tri-thiophenes have been prepared by electrochemical polymerization. Compared with the Co^Шcorrole monomer, the electrocatalytic hydrogen evolution performance was significantly improved. In particular, when the molar ratio of Co^Шcorrole and bithiophene is 10:1, the conductive polymer prepared shows better electrocatalytic hydrogen evolution performance. In addition, the effects of chain length of thiophene on the hydrogen evolution performance were compared, and Co^Шcorrole-trithiophene has the greatest improvement on the hydrogen evolution performance, followed by bis- and mono-thiophene.
